Which rooms to optimize with reverberate®
reverberate® is designed for you to plan acoustics spaces like gyms, classrooms, offices and homes. Whether you are an architect, engineer, or simply curious – with reverberate® you can calculate the reverbation time quickly and easily online and compare with the required values according to DIN 18041 and ASR A3.7 – based on a new calculation model by Zhou et al. (2021).
Use reverberate® in the following rooms – and many more:
Homes
Classrooms
Offices
Studios
How to optimize acoustics with reverberate®
Customize your room’s acoustics
Every surface within the room can be subdivided and covered with absorbing materials. Choose from our extensive database of acoustically effective materials or input your own values. Additionally, you can adjust the scattering properties of the surfaces and add furniture and people to the room.
Accurate reverberation time calculation
Based on your inputs, reverberate® precisely calculates the reverberation time within the room. The result is displayed alongside the required range specified in the chosen standard.
Iterative optimization
If the calculated reverberation time falls outside the desired range, you can iteratively optimize the room’s acoustics until the requirements are met.
Scientifically validated results
reverberate® utilizes a cutting-edge, scientifically validated calculation model, that ensures that the room acoustic planning in reverberation corresponds to the performance of the actual room. This safeguards the planning against longer reverberation times in the completed room.
Export functionality
Export your results as a PDF and download it for later use and documentation. Listen to the acoustics of the room with precise and realistic auralisation, with taking the frequency related reverberation into account.
New features
Soon you can make your projects even more sustainable! In mid-2025, we’ll introduce an integrated assessment of the environmental footprint of your acoustic solutions. This feature will be available to you free of charge after the release.

The science behind reverberate®
Unlike other software solutions that mostly use the simple reverberation time calculation according to Sabine, reverberate® takes the absorption distribution and scattering coefficients of the surfaces in the room into account.
For this purpose, the sound field is divided into three spatial directions and the diffuse field. Frequency dependent decay curves are calculated for all subsystems and summed, taking into account the acoustic properties of all surfaces. The reverberation times calculated from this approach is much more reliable and realistic, a complex simulation is therefore not required.
All calculation methods behind reverberate® were developed in extensive scientific studies and validated by measurements. We have published the theory behind reverberate® as a peer-reviewed paper in Applied Acoustics. With reverberate®, we are now making this innovative calculation method usable. Of course, reverberate® also offers the calculation of the reverberation time according to Sabine for comparison.
